The water outlet on my Y block leaks and it is driving me nuts-the polite forum nuts that is. I have gone through two sealings with aviation forma gasket and two with gaska cinch. I even bought a new outlet to make sure the surface was flat and not pitted. This last time I let it set up for two days (followed the instructions as far as application) and it drips out the bottom. I am not going to use RTV-Black this next time and make a mess. Any other thoughts before I have to pull the manifold and have it sanded smooth?

Thanks,

Mike
